Christopher Lloyd has been set to play Uncle Martin, the curmudgeonly Martian, in Walt Disney Pictures’ “My Favorite Martian,” a feature revival of the 1960s sitcom to be directed by Donald Petrie.In the pic, newswriter Tim O’Hara runs across a Martian whose spaceship has crashed landed on Earth and is anxious to repair it and get back home. Though Tim at first sees the Martian discovery as the scoop of a lifetime, he soon comes to care about the alien’s well being, and refuses to reveal him to the authorities, instead telling others that the Martian is his uncle. The studio is currently in the process of casting the Tim O’Hara character. Sources say it is looking at a July start. In the series, which ran from 1963-66 on CBS, Bill Bixby played Tim, while Ray Walston played the Martian, who looked human but had retractable antennae and could turn invisible. The project had been set up at Warner Bros., with Martin Short at one time in mind for the Martian, and Joe Dante attached to direct. But the pic was put into turnaround last year and landed at Walt Disney Pictures. Producers will be Robert Shapiro, Jerry Leider and Barry Bernardi.
